How those broken drill bits we all have were made.

Those are much higher quality than the bits I break.  I guarantee you I'm not paying for 4-5 hours of setup per bit at whatever wages that guy is getting paid.

Interesting video. It is a typical tungsten-carbide PC board  drill bit. I use those a lot in my hobbies.  While the bits down to #80 can be relatively inexpensive (the re-sharepened ones), anything smaller than #80 gets quite pricey (and extremely brittle).  I'm pretty sure the manufacturing process is similar for the larger bits (but likely more automated).
